Embodiment

[0028] In this embodiment, according to the flow process of accompanying drawing, the flow direction of reaction material between reactors is successively: R 1 →R 2 →R 3 →R 4 , the regenerated catalyst is divided into three parallel paths: the flow direction of the first path is R 1 →R 4 , the second path flows to R 2 , the third way flows to R 3 , and the test results are listed in Table 1.

[0029] It can be seen from Table 1 that under the same severity, the C5+ liquid product yield of the co-current continuous reforming process is 1.3 percentage points higher than that of the co-current process and the counter-current process, and the hydrogen production rate is higher than that of the co-current process and the counter-current process. Craft was 0.1 percentage points and 0.04 percentage points higher, respectively.

Abstract

The parallel flow catalyst reforming process with multiple movable bed reactors includes: making material oil flow from the first movable bed reactor to the last one successively for the material oil to contact with the reforming catalyst in different reactors, separating the reformed oil in subsequent separator, regenerating catalyst out of the second movable bed reactor through the last one, separating the regenerated catalyst into several parts, and feeding the first part to the first reactor and the last reactor successively while feeding the other parts to the second reactor through the last reactor but one separately. The said process has raised liquid product yield and hydrogen yield.

Description

technical field [0001] The invention relates to a method for catalytic reforming of naphtha, more specifically, belongs to a method for catalytic reforming of moving bed. Background technique [0002] Catalytic reforming unit is an important part of the oil refining and petrochemical industry. With the increase in the demand for motor gasoline, the improvement of environmental protection requirements, the wide application of basic chemical raw materials such as light aromatics (B, T, X) and the construction of new refineries The increase in demand for hydrogen in hydrogenation units has led to greater development of catalytic reforming units at home and abroad. As of 2000, my country had 55 sets of catalytic reforming units with a total processing capacity of 16.47 million tons per year, including 14 sets of continuous reforming devices with a capacity of 8.89 million tons per year, accounting for 54% of the total processing capacity. The continuous ...
